Bayshore Eyeglass Store

At our Bayshore eyeglass store, we explains to all our patients that unlike an eye test, an optical prescription is not a straight measurement of your ability to see. It does not compare eyesight with someone who has perfect vision, the way an eye chart does. Instead, the numbers on your prescription are the specific power that is needed to correct your vision to normal. Basically, with an accurate optical prescription, corrective lenses in your glasses bend the light rays to focus more directly onto your retina. The amount of correction necessary is written as your prescription and is what is used to correct your vision.

If you wear glasses, you certainly know they help you to see better, but you may not know how they specifically correct your vision. Whether for nearsightedness or farsightedness, eyeglasses work in the same way. When the lens in your eyeglass is curved, it bends the light rays that hit your eyes, so you can see images clearly. The experts at our Bayshore eyeglass store, Vision Center, wants all of our patients to know that understanding how glasses correct your vision, begins with a basic understanding of how your eye works. At the back of your eye is your retina, which is a layer of cells that reacts to light. The reaction is sent to your brain, and your brain translates the cells activity into an image, or the thing that you actually see.

When you look at something, the light rays focus inside your eye, or come together. When you have perfect vision, the light rays focus directly on to the surface of your retina. Because the retina is curved, the image must also shrink, and needs to be curved, because the retina is curved. Your pupil and cornea are responsible for shrinking, focusing, and curving the image and if any of them have any irregularities, your vision becomes blurry. Eyeglass lenses are curved pieces of glass and the curvature of the lens bends the light rays as they move towards your eye. This helps the rays focus on your retina, instead of behind it or in front of it. Statistics show that over 160 million people in the United States alone wear corrective lenses and perfect vision is very rare. If you’re one of those 160 million people, come down to our Bayshore eyeglass store and shop for a new pair of eyeglasses to improve your daily vision.
